The book "Degradable Polymers" offers a comprehensive analysis of developments in the field of biodegradable polymers, particularly regarding their applications in biomedicine and agriculture. The second edition places a stronger emphasis on composting as a method for creating value from waste, which requires a better understanding of the environmental impacts of plastics and their degradation processes. Additionally, the discussion on polymers from renewable resources and their long-term sustainability, as well as ecological advantages compared to conventional biodegradable plastics, is continued. This specialized book is aimed at academic and industrial scientists working with the application of plastics in various fields, as well as students of environmental sciences and policymakers addressing the impacts of plastics on the environment.
